The reason why hair may grow in different lengths is due to a variety of reasons such as genetics, stress, and breakage.
The average rate of hair growth is around six inches per year. However, it is not uncommon for people to experience uneven hair growth. There are several reasons why this may be the case.
One reason why your hair may be growing at different lengths is due to genetics. Everyone’s hair grows at different rates and is subject to different genetic factors. For example, if your parents or grandparents had uneven hair growth, you may be more likely to experience the same.
Another reason why your hair may be growing unevenly is due to stress. When you are experiencing a lot of stress, it can affect the way your hair grows. This is because stress can cause your hair to enter into a resting phase, during which time it doesn’t grow as quickly. Breakage can also cause uneven hair growth, as damaged hair will grow back more slowly than healthy hair.
It also depends on whether your hair is right- or left-handed. Studies have shown that people with right-handed hair are more likely to have evenly distributed growth, while those with left-handed hair are more likely to have uneven growth. This is because the way in which our hair grows is influenced by the direction in which it is curled.
There are several reasons why your hair may be growing at different lengths. Genetics, stress and breakage can all play a role. Additionally, the way in which your hair grows can be influenced by whether it is right- or left-handed.
